Implementing Security, piece II: Hardening Your UNIX/Linux Servers | killexams.com true questions and Pass4sure dumps

Continuing with piece 2 of this two-article series, Joseph Dries helps you continue to expand upon your list of basic security processes by looking at UNIX/Linux hardening, protecting your servers from network based TCP/IP attacks, and utilizing centralized logging servers.

This article was excerpted from The Concise lead to Enterprise Internetworking and Security.

"A commercial, and in some respects a social, doubt has been started within the terminal year or two, whether or not it is prerogative to debate so openly the security or insecurity of locks. Many well-meaning persons suppose that the discussion respecting the means for baffling the hypothetical safety of locks offers a premium for dishonesty, by showing others how to breathe dishonest. This is a fallacy. Rogues are very keen in their profession, and already know much more than they can school them respecting their several kinds of roguery. Rogues knew a helpful deal about lockpicking long before locksmiths discussed it among themselves, as they absorb lately done. If a lock—let it absorb been made in whatever country, or by whatever maker—is not so inviolable as it has hitherto been deemed to be, surely it is in the interest of honest persons to know this fact because the lying are tolerably positive to breathe the first to apply the learning practically; and the spread of learning is necessary to give impartial play to those who might suffer by ignorance. It cannot breathe too earnestly urged, that an acquaintance with true facts will, in the end, breathe better for complete parties." —Charles Tomlinson's "Rudimentary Treatise on the Construction of Locks," published around 1850

It has been said that the wonderful thing about standards is there are so many to choose from. The identical election is available in the UNIX arena. There are two basic flavors, BSD-derived and AT&T System V-derived. BSD-derived UNIX systems comprise OpenBSD, FreeBSD, NetBSD, BSDi, MacOS X, and SunOS 4. System V-derived UNIX systems comprise HP-UX and Solaris (SunOS 5). Other UNIX systems, such as AIX, provide commands that will act BSD-ish or System V-ish, depending on how they were invoked. Linux is not derived from any UNIX, but depending on the distribution, borrows from both BSD and System V semantics. Actually, Linux itself is just the operating system kernel and supporting drivers. Most Linux distributions consume the GNU system (http://www.gnu.org), thus they are called GNU/Linux distributions. There are hundreds of available GNU/Linux distributions, but even the "top 5" are different in their default commands, startup scripts, filesystem layout, included utilities, and packaging systems.

What does this affect to you? Unlike Windows NT, including Windows 2000, it is a far more knotty process to narrate how to harden a UNIX/Linux server. This next section provides some common procedures that can breathe applied across UNIX versions and GNU/Linux distributions. Following that are some pointers to alive documents on the Internet, which track available data and releases, and depart into a more particular account of how to harden a server for a particular task.

Common Steps for Hardening UNIX/Linux Servers

The process of pile a UNIX or GNU/Linux server for consume as a firewall or DMZ server begins with installation. Eliminating points of attack, such as filling the filesystem, or removing unnecessary libraries and services, is equivalent to removing possible entry points for intruders.

Some common guidelines for configuring UNIX servers with a more secure default stance are available from CERT's Web site at ftp://info.cert.org/pub/tech_tips/UNIX_configuration_guidelines.

Partition for Protection

Besides having divide partitions for the obvious, such as SWAP and /tmp, you should protect against out-of-disk-space denial-of-service attacks. Intruders might try to create extravagant generation of logging data or fill your file system with large files through FTP or mail spool. The best route to protect against this is to segment the filesystem hierarchy into divide physical partitions.

The root partition / can breathe petite because it generally contains just the kernel—the necessary files, libraries, and configuration for booting in /bin, /sbin, /etc, and /lib. Access to the attached devices is provided through the /dev and /devices directories. Many GNU/Linux distributions store kernels and attribute data in the /boot directory, whereas kernel libraries are stored under /lib.

The /usr partition is normally where user-accessible applications are stored. Normally, /usr does not contain data or configuration files that change; therefore, an added security measure can breathe mounted as read-only.

The /var partition stores system logs and data services such as mail, Web, databases, printing, running services, package management, and so on. On a mail server, you might want to accomplish /var/spool/mail, or /var/mail in Solaris, a divide partition, or—even better—a divide disk array. If you only create one divide partition from /, /var is the one you should separate.

The /usr/local directory structure, and in Solaris the /opt directory, often contains locally installed optional software, configuration files, and data. /usr/local is normally not affected by operating system upgrades. Depending on how you consume those directories, they too can breathe mounted as read-only.

These are suggestions and guidelines only, and are different from recommended settings for a system that contains user accounts, usually in /home.

Disable Extraneous inetd Services

inetd is the UNIX "Internet Super Server." It is a daemon process that is invoked at boot time and reads in a flat file configuration database normally organize at /etc/inetd.conf. inetd listens for incoming connections on the defined IP ports. When a connection is initiated on a defined port, it invokes the configured program to service the request. After the connection is finished, the process invoked to service that request terminates. This was originally designed to lighten the load and resources required for systems.

There are a number of services enabled through inetd, and almost complete of them should breathe disabled for pile firewalls and DMZ servers. Besides normally disabling FTP, TFTP, Telnet, and the Berkeley r* commands, disable the following:

  • in.named—BIND name services daemon. Except for your DNS servers, you should not breathe running DNS on your firewall or DMZ servers.

  • in.fingerd—Finger daemon that can breathe used to reveal user information and lists of users who are logged in. There is no reason to advertise that information to would-be intruders.

  • daytime—Connections to this service pomp the date and time on the system in a string format. Getting the date and time of a system is useful for an intruder trying to implement replay attacks.

  • time—Connections to this service return the time as a 32-bit value representing the number of seconds since midnight 1-Jan-1900. carry out not provide intruders with your exact system time.

  • echo—This is a diagnostic service that echoes incoming data back to the connecting machine.

  • discard—This is a diagnostic service that does not echo (thus discarding) the incoming data stream back to the connecting machine.

  • chargen—This is a diagnostic service that automatically generates a stream of characters sent to the connecting machine.

  • systat—Connections to this service provide a list of complete processes and their status.

  • netstat—Connections to this service provide a list of current network connections and their status.

  • Install and Configure tcp_wrappers

    Install and configure Wietse Venema's tcp_wrappers on both your firewall and DMZ servers. tcp_wrappers allows you to define access control to various services, depending on a limited set of criteria, such as username, IP address, or DNS domain.

    You might breathe asking why it's necessary to configure and install additional products when your firewall will breathe doing the identical thing. And that's a convincing question. The retort is to avoid solitary points of failure, and to provide security in layers. If one layer is pierced and bypassed, other layers will breathe standing guard behind the breach.

    tcp_wrappers are lightweight and extremely useful on internal servers; not just on firewalls and DMZ servers. hold in reason that most information security breaches, intentional or accidental, betide internally. It's only the external defacements, massive distributed denial of service (DDoS) attacks, virus-du-jour, and stolen credit card databases that grab the press. That, and misplaced arduous drives with highly sensitive nuclear information.

    tcp_wrappers absorb two main files that allow access to the individually defined services. The following two files are checked for rules governing access to individual or wildcard services:

    /etc/hosts.allow /etc/hosts.deny

    Like most firewalls, access is granted or denied on the first matching rule. The rules are checked in order, first in hosts.allow and then in hosts.deny.

    Care should breathe taken when using the KNOWN or UNKNOWN wildcards. complete will always match whatever criteria you are testing. Read the hosts_access manual page included with tcp_wrappers for further details on syntax and rules setup.

    tcp_wrappers is installed and configured by default on most GNU/Linux distributions and BSD releases. For those UNIX systems that carry out not absorb tcp_wrappers installed by default, they can breathe organize at ftp://ftp.porcupine.org/pub/security/index.html. Retrieve the source, compile, and install the binaries on the servers.

    Lock Down Your DNS Server

    The Berkeley Internet name Daemon, or BIND, is the reference implementation of the name service providing DNS for the Internet. The Internet Software Consortium (ISC) is accountable for implementing and maintaining BIND. There are three basic versions of BIND: BIND 4, BIND 8, and (recently) BIND 9.

    BIND 4 has been around forever, and has its share of exploits. Only very ripen versions of UNIX systems and GNU/Linux distributions came with BIND 4. Still, you'll breathe surprised how many installations noiseless absorb the older BIND 4 running. You should upgrade to a newer version of BIND. The unfortunate thing is that the file format defining the zones served by the server has changed. There are conversion scripts, but there is positive to breathe some hand editing.

    BIND 8 is the current stable release, and offers many more features and better control and granularity in access control. The settings described later are discussed with BIND 8 in mind.

    BIND 9 was released late in 2000. It offers many modern features, such as IPv6 support, DNSSEC, replete Dynamic DNS, incremental zone transfers, multiple views (internal, external, and so on) from a solitary server, and scalability improvements. If any of those features are censorious to your configuration, you should investigate using BIND 9; otherwise, it's best left to the adventurous.

    Although almost complete UNIX systems and GNU/Linux distributions arrive with BIND as the name server, it is censorious you accomplish positive you are at a recommended release. Before deploying a DNS server, internally or on the DMZ, accomplish positive it is at least version 8.2.2-P5. Any version prior to that has sedate exploits. This warning should not breathe ignored. The Internet Software Consortium themselves absorb issued a statement that if you are running any version of BIND prior to 8.2.2-P5, you should assume your server has already been compromised. Check your UNIX system or GNU/Linux distribution. If the version of BIND is not at least 8.2.2-P5, check with your vendor for upgrades. If an upgrade is not available, you can compile a version of BIND yourself on a workstation, and install the binaries on your server. The source code can breathe organize at http://www.isc.org/products/BIND/.

    First, restrict zone transfers to specific secondary servers in your primary zones. The acl command allows you to define an access control list composed of blocks of addresses to breathe used with a named identifier. Using ACLs provides a self-documenting method of administrating the named.conf configuration file. In the following example, they define two ACLs comprising their externally visible DNS servers and the secondary servers at their ISP:

    acl your-company-dns { 172.16.30.12; 172.16.30.24; }; acl your-ISP-dns { 199.177.202.10; 204.95.224.200; };

    The following allow-transfer option directive placed in your named.conf file will default complete defined zones to only allow transfers for the defined hosts:

    options { allow-transfer { your-company-dns; your-ISP-dns; }; };

    You can override the allow-transfer statement in the options directive by placing the allow-transfer statement in the zone definition:

    zone "yourdomain.com" { character master; file "db.yourdomain-com"; allow-transfer { 172.16.30.12; 192.168.71.200; }; }

    The default allow-transfer option will preclude zone transfers to hosts not specified in the ACLs. However, if you want to restrict complete zone transfers on your secondary servers and any secondary zones on your primary servers, consume predefined match list none. This can breathe accomplished with the following allow-transfer directive in your zone definitions:

    zone "yourdomain.com" { character slave; file "db.yourdomain-com.s"; masters { 192.168.71.1; }; allow-transfer { none; }; };

    Finally, because you will breathe allowing recursive queries through your servers, it's best to enable access control lists for your internal networks. Using a nested, named acl with the allow-query option in the zone definition, you can then restrict recursive queries to internal hosts only as seen in the following example:

    acl internal-net { 192.168.71.0/24; }; acl dmz-net { 172.16.30.0/24; }; acl trusted-hosts { localhost; internal-net; dmz-net; }; zone "yourdomain.com" { character master; file "db.yourdomain-com" allow-query { trusted-hosts; }; };

    Que's Concise lead to DNS and BIND by Nicolai Langfeldt is a wonderful resource to further grok BIND configuration and maintenance.

    Tighten Sendmail Default Options

    Send mail comes with just about every UNIX/Linux installation as the default mail transfer agent (MTA). As a result of being so widely installed, it has been estimated that sendmail handles a majority of the email on the Internet. Because it runs as suid root, sendmail exploits affect millions of machines.

    sendmail version 8.11.0 is available at the time of publication, and supports modern features such as STARTTLS and SMTP AUTH encryption. Upgrade to the newest version available, if possible, but delight accomplish positive that you are running a version no later than version 8.9.3 because of security exploits.

    To enable the Realtime Blackhole List feature, consume the following in your sendmail.mc file:

    FEATURE(rbl)dnl

    Additionally, you might want to disable the SMTP VRFY and EXPN commands in sendmail. These commands are often used by intruders to accumulate information about your system:

    define(´confPRIVACY_FLAGS', ´novrfy,noexpn')dnl

    There are several additional flags you can set to accomplish sendmail absorb a more secure stance:

  • authwarnings—Add X-Authentication-Warning header in messages on positive conditions that might argue mail system spoof attempts.

  • needmailhelo—Require that the sending site uses the SMTP HELO command first when connecting to dispatch email.

  • needexpnhelo—Require that the sending site uses the SMTP HELO command before allowing any EXPN usage.

  • needvrfyhelo—Require that the sending site uses the SMTP HELO command before allowing any VRFY usage.

  • noreceipts—Disable Delivery Status Notification (DSNs) of delivery and read receipts.

  • goaway—Set complete flags except restrictmailq and restrictqrun.

  • restrictmailq—Prevent users from using the mailq command to view the contents of the mail queue.

  • restrictqrun—Stop users from processing the queue.

  • Better than sendmail: Making Postfix Your MTA

    According to its Web page, Postfix's goals are "to breathe fast, light to administer, and secure, while at the identical time being sendmail compatible enough to not upset existing users."

    Postfix was primarily written by Wietse Venema of tcp_wrappers fame. Postfix was designed to breathe modular, thus Postfix is not a solitary executable enjoy sendmail; rather, Postfix comprises a collection of specialized programs that accomplish specific tasks. complete the programs except for the master control process (oddly called master because it runs without root privilege) quicken as nonprivileged users, limiting the damage an attacker can inflict on your system. Because of the speed, ease of configuration (and thus less haphazard of misconfiguration), and security, it is recommended that you investigate replacing sendmail with Postfix. For those of you who carry out not dream in sendmail.cf syntax, Postfix will accomplish email administration both easier and more secure.

    Postfix is now distributed with most GNU/Linux and BSD releases, although it is not often installed by default. Usually, it is a simple matter of installing it via your package management system, or (in the BSD case) via the ports collection.

    If you are using an operating system that does not dole Postfix, despair not. You can download and compile the sources easily on a evolution workstation and then install the binaries on your mail server. The sources, FAQs, and documentation can breathe organize at http://www.postfix.org/

    Linux-Specific Tasks

    There are many GNU/Linux distributions out there. Each vendor has its own installation process, which usually changes between modern versions of the vendor's distribution. The "forerunners" of GNU/Linux distributions are Red Hat, SuSE, TurboLinux, Mandrake, Caldera, Slackware, and Debian. That does not affect specifically that you should consume any one of them because the lofty number of distributions allows vendors to tailor their GNU/Linux distributions to specific tasks such as embedded systems, routers, and firewalls. Take the time to carefully investigate the available distributions, and determine which best fits your needs.

    With that said, two of these universal distributions stand out, but for different reasons. Red Hat, because it has had the most name recognition, and is usually the first to fetch any sort of corporate back in the route of commercial software or commercial technical service. Many vendors, such as Oracle, IBM, and Check Point, absorb released products for Red Hat-specific distributions. This does not affect that those software releases will not quicken on other GNU/Linux distributions, but if there is a problem, the vendor might not back your installation of its product on a non-Red Hat distribution.

    Debian is the second distribution that deserves mention. First, not because it is entirely free, but because it is maintained by a nonprofit organization made up entirely of volunteers. These volunteers are highly motivated by attribute and pride in their efforts to accomplish Debian the most stable and completely 100% free distribution available. Debian has proven to breathe extremely stable and light to manage and upgrade remotely. The upgrade process is by far the easiest of any of the GNU/Linux distributions. Debian installations can breathe upgraded without the exigency for reboots, replacing every installed package and running process excepting the kernel. Additionally, the Debian packaging system and its front ends allow extremely fine-grained control over which packages, utilities, libraries, and files exist on your system. Debian furthermore is currently available on six different architectures, with more than 3,900 included software packages to select from when installing.

    For both Debian and Red Hat installations, you should choose custom installations, and select the individual packages you want on your system. There should breathe no exigency to install evolution packages, any of the modern KDE or GNOME desktops, and certainly not X Window. Unfortunately, neither distribution yet has a minimal secure server or firewall predefined install-set.

    During the installation process, you should choose to enable shadow password file support; choose to consume MD5 hashes for the passwords rather than the orthodox crypt function. If you miss these options during the install, you can change them after installation. In Red Hat, consume the setup utility. In Debian, you can consume the shadowconfig utility to enable or disable shadow passwords. To enable MD5 hashes, you absorb to edit the confiscate files under /etc/pam.d to comprise md5 on the password lines.

    You should furthermore enable ipchains support, even if this is an application server on the DMZ. ipchains provides additional layers of security, and allows you to protect the server from traffic should the firewall fail for some reason. A sample ipchains configuration is discussed later in the article.

    You should additionally read and monitor the security and errata/updates lists from your distribution vendor. With Debian, it is extremely light to automatically install security updates using the apt-get utility. For Red Hat installations starting with the 6.0 release, there is the up2date utility to retrieve updated packages for your release.

    For those people who choose to install Red Hat Linux, there is a security-related project called Bastille Linux, whose train is not just to harden your Linux installation, but to educate the administrators on how to harden the system. Bastille Linux supports Red Hat and Mandrake Linux distributions with project goals to become distribution, and UNIX flavor, agnostic. The Bastille Linux product is a set of scripts that asks a chain of questions and then allows you to apply those modifications to your system. The questions narrate what needs to breathe done, why it should breathe done, and why you might not want to carry out it. It is very educational, especially for those administrators just getting close with Linux. Bastille Linux can breathe organize at http://www.bastille-linux.org/.

    Another excellent source of information for administrators is the Linux Administrator's Security Guide. It covers an extremely wide array of topics related to Linux and security. You can find the Linux Administrator's Security lead online at http://www.securityportal.com/lasg/.

    Solaris-Specific Tasks

    Solaris has four default install-sets: Core, End-User, Developer, and Entire Distribution. Installing any install-set higher than the Core installation will enable more services than are required for DMZ servers or firewalls. In reality, you can often remove a significant percentage of the default Core install-set, depending on your server's application requirements.

    For Solaris-based servers, there are several excellent documents from Sun in its Blueprints Online archive at http://www.sun.com/software/solutions/blueprints/online.html. The following three papers are excellent starting points for pile secure Solaris servers:

  • "Solaris Operating Environment Minimization for Security: A Simple, Reproducible and Secure Application Installation Methodology" by Alex Noordergraaf and Keith Watson. Although this paper specifically covers the iPlanet Web server requirements, similar requirements are necessary for using Apache or other Web servers.

  • "Solaris Operating Environment Security" by Alex Noordergraaf and Keith Watson. An overview of universal security options on a Solaris server. This paper includes some specifics for the SPARC architecture; however, most of the material is applicable to Intel architectures as well.

  • "Solaris Operating Environment Network Settings for Security" by Alex Noordergraaf and Keith Watson is another excellent paper on kernel tuning and application parameters that affect network security.

  • As a matter of fact, Sun's Blueprints Online is a wealth of whitepapers outlining Best Practices regarding Solaris Operating Environments, whether it is a DMZ Web server, firewall, or internal highly available database cluster.

    Lance Spitzner furthermore has an excellent Solaris hardening document that details the hardening process for pile a Check Point FireWall-1 firewall on several recent versions of Solaris (through version 8) for the Intel and SPARC platforms. The alive document resides at http://www.enteract.com/~lspitz/armoring.html.

    Finally, there is an equivalent to the Bastille-Linux hardening scripts for Solaris called TITAN. The TITAN project and documentation can breathe organize at http://www.fish.com/titan/.

    OpenBSD-Specific Tasks

    This section concentrates on OpenBSD 2.7, which is one of the three more eminent BSD variants; the others being NetBSD and FreeBSD. Each variant has focused on a different problem: NetBSD is the most portable, FreeBSD has the best performance, and OpenBSD is the most secure.

    One of the much strengths of OpenBSD is the highly secure default stance of a default install of OpenBSD. The OpenBSD Web site claims "three years without a remote cavity in the default install, only one localhost cavity in two years in the default install." Almost complete services are disabled until the administrator has enough savor to properly configure them.

    Two additional changes necessary for an OpenBSD box to become a firewall are to disable sendmail and enable IP filter support. Both changes are made to the identical file, /etc/rc.conf. To disable sendmail, change

    sendmail_flags="-q30m"

    to

    sendmail_flags=NO

    To enable IP filter support, you must change

    ipfilter=NO

    to

    ipfilter=YES

    Additionally, if you will breathe doing Network Address Translation (NAT), providing transparent proxying, or providing back for FTP, you must enable the ipnat option by setting ipnat=YES. Syntax for IP filters will breathe covered briefly later in the chapter.

    You may jump straight to the month of your choice: January, February, March, April, May, June, July, August, September, October, November, or December.

    The Linux Weekly intelligence begins publication. The very first issue, dated January 22, was a just a tiny hint of what LWN was to become. Since then we've gotten better at it, and the Linux world has gotten much more complicated. It has been an consuming adventure.

    [Netscape]Netscape announces that they will release the source to their browser under a free software license. This almost certainly remains one of the most censorious events of the year; it opened a lot of eyes to what Linux and free software could provide.

    [RHAD] Red Hat Advanced evolution Labs is founded. It has since become one of the higher-profile places where people are paid to develop free software, and an censorious component of the GNOME project. RHAD is able to attract developers enjoy "Rasterman" and Federico Mena Quintero.

    The Stampede Linux distribution is announced. Actually, this happened in December, but the intelligence took a while to spread... Stampede positions itself as a high-performance "real Linux hacker's" distribution.

    Word gets out that parts of the blockbuster film "Titanic" were rendered on Alpha machines running Linux. This was another censorious step in the "legitimization" of Linux - everybody had heard of The Titanic, and some of its success seemed to rub off on everything associated with it.

    [Qube] The Cobalt Qube is announced and immediately becomes a favorite in the trade press due to its lofty performance, low price, and cute form factor. Cobalt's Linux engineering is done by not a soul other than David Miller, source of much that is helpful in the Linux kernel.

    [prize] The Linux user community wins InfoWorld's technical back award; Red Hat 5.0 furthermore won their Operating System award. But it was the tech back award that truly opened some eyes; everybody had been saw that Linux had no support. This was the genesis of the discontinue of the "no support" argument.

    [opensource] Red Hat announces that their installation back staff is running behind. They are a victim of their own success, and hope for patience while they fetch their act together.

    Linux according to Jesse Berst "I deem it's much if you are willing to promote Linux to your boss. As long as you are vigilant of the risk you are taking. The risk of getting fired." (Feb. 16). "Is a Linux takeover likely? Give me a break. Of course not." (June 23). "I personally deem Windows NT will breathe the mainstream operating system within a few years." [...] "My belief: Linux will never depart mainstream" (Sep. 9). "I've always said that Linux could become a sedate challenger to Microsoft's Windows NT." Sep. 28).

    Eric Raymond and friends arrive up with the "open source" term. They apply for trademark status, and build up the opensource.org web site. Thus begins the formal endeavor to thrust Linux for corporate use.

    Linus Torvalds and Richard Stallman win the EFF Pioneer award. The award recognizes their contributions to electronic freedom. Strangely, complete mention of this seems to absorb vanished from the Electronic Frontier Foundation web site.

    Caldera 1.2 is released. Unlike Red Hat, which had been shipping libc6 based systems for some time, Caldera sticks with the tried and loyal libc5.

    The OpenBIOS project is launched, in the belief that no system is free if it depends on proprietary BIOS code. A web page is set up for the project.

    [GGI] Major battles rage over whether GGI belongs in the Linux Kernel. GGI, the "Generic Graphics Interface," seeks to produce a better defined, better supported interface to video cards on Linux and other systems. Interestingly, GGI had made no request for kernel inclusion at this time. No resolution was reached, but better communications with a number of kernel hackers did result from this episode.

    The Linux universal Store opens; this is "the first walk-in Linux store." (Web page here).

    [Learning tree] Learning Tree, International adds a Linux administration course to their lineup. This course is offered frequently in the U.S. and Britain. "The attribute of Linux software has improved dramatically, making it a low-cost, reliable, supported computing platform confiscate for the commerce environment."

    Consumer advocate Ralph Nader asks the large PC vendors (Dell, Gateway, Micron...) to tender non-Microsoft systems, including systems with Linux installed. (See InfoPolicy Notes).

    Sun offers 70% discounts for people interested in "upgrading" from Linux to Solaris.

    [Debian] [Sendmail logo] Bruce Perens, once leader of the Debian project, quits entirely in the wake of disagreements on how the project should proceed.

    Sendmail, Inc. is formed by Eric Allman, in an attempt to accomplish money selling sendmail back services while keeping the basic sendmail code free.

    John Kirch releases his "Microsoft Windows NT Server 4.0 versus Unix" paper. This paper remains one of the best advocacy pieces out there, and should breathe required reading for anybody contemplating deployment of either technology.

    [Mozilla] The Mozilla source code hits the net. Netscape throws a huge party. The code is downloaded complete over the world, and people start hacking. modern features, such as stout encryption and a Qt port, are added almost immediately.

    Linus makes Inter@ctive Week's "25 Unsung Heroes of the Net" list. He is in helpful company, joining names enjoy Steven Bellovin, Van Jacobson, Peter G. Neumann, and others. April was maybe about the terminal time that Linus could breathe said to breathe an "unsung" hero.

    Linus announces Linux 2.1.92 and declares a 2.1 feature freeze. The announcment goes as far as to thunder "...there are probably noiseless bugs with some of the modern code, but I'll freeze modern features for the upcoming 2.2 kernel." This freeze turned out to breathe rather slushy, to thunder the least.

    The Open Group announces a modern licensing policy for the X window system. modern versions of X will breathe proprietary and only available to paying customers. They immediately withhold some security bugfixes from universal distribution. XFree86 decides that it can not live with the modern licensing, and declares its intent to depart its own way.

    [NPR] Linux is covered by the U.S. National Public Radio news, marking one of its first appearances in the mainstream, non-technical press.

    O'Reilly holds the "first ever" Free Software Summit, featuring Larry Wall, Brian Behlendorf, Linus Torvalds, Guido van Rossum, Eric Allman, Phil Zimmermann, Eric Raymond, and Paul Vixie.

    The Linux Weekly intelligence daily updates page debuts. Despite LWN's intent to hold the its weekly focus, the daily page eventually exceeds the weekly newsletter in traffic. The Linux events calendar is furthermore announced.

    Linus 3.0 is announced; the birth of Linus's second daughter causes much joy, and substantial disruption in kernel evolution as complete drudgery stops and many patches fetch lost. Some grumbling results as it becomes lucid just how dependent the entire process is on Linus's incessant presence.

    RH  back partner logo[Avalon] Red Hat announces their commercial back program, based on a worldwide network of "support partners," of which Eklektix, Inc., the producer of the Linux Weekly News, is one.

    The Avalon Beowulf cluster at Los Alamos goes on line and immediately powers itself into the list of the fastest computers on the planet.

    Eric S. Raymond publishes "Homesteading the Noosphere" on the web; This paper gives his view of how economics of open source software can work.

    Kernel hacker Alan Cox goes to drudgery for Red Hat.

    Bruce Perens proposes a modern Linux distribution (proposal here) based on his savor with Debian. This distribution never comes about, but much of what's there later gets folded into the Linux standard basis project.

    [Project Heresy C|Net's "Project Heresy" starts a high-profile attempt to drudgery using only Linux. The result was a long chain of articles and "radio" programs, complete on the Project Heresy page.

    Sun Microsystems joins Linux International.

    [Google] The "Google" search engine pops up. Not only is it one of the best search engines around, but it's based on Linux and features a Linux-specific search page.

    Sm@rt Reseller reports that Oracle and Informix absorb no plans to back Linux. "In fact, many doubt that Linux-no matter how stable or how cheap-can ever compete in the corporate marketplace alongside the well-funded Windows NT and Solaris." (article here).

    [SuSE] The SuSE 5.2 distribution is released.

    [Corel] Corel formally embraces Linux. The Netwinder products are featured, and they pledge their back for the Linux system.

    The Association Francophone des Utilsateurs de Linux et des Logiciels Libres (AFUL) is formed in France. AFUL promptly becomes a obligate in French computer circles.

    O2 expansive databases start to arrive. back for Linux is announced by Computer Associates for their Ingres system, and by Ardent Software for their O2 protest database.

    The Linux Core/Layers project was announced and became the first in a chain of attempts at creating standards for Linux systems. The Core/Layers page noiseless exists, but this project is no longer vigorous in this form.

    "But Linux is a communist operating system in a capitalist society. Its popularity is going to lead toward its fragmentation....The expansive problem with Linux is that it has no obvious direction. It's in the prerogative residence at the prerogative time, but its 15 minutes are nearly up." (PC Week, May 22).

    The Linux Weekly intelligence moved to its own domain at lwn.net.

    A proposal goes out to create the Linux standard basis (LSB) project. This proposal, signed by a large number of Linux luminaries, was discussed at Linux Expo and formed into a project, with Bruce Perens at the head. Numerous editorials were written and posted on FreshMeat; the list can breathe organize on the LSB web page. The LSB then disappeared from view for a few months.

    And, yes, Linux Expo was held; a helpful time was had by all.

    Red Hat 5.1 was released and immediately started accumulating rather more than the accustomed number of updates (partly as a result of the Linux Security Audit program). There was talk of "Red Hat 5.1 service pack 1" as a result. 5.1 did eventually stabilize into a solid release.

    "First, let me thunder that I am uniquely unqualified to write about this week's topic. enjoy most of you, I've never used Linux....Linux has a snowball's haphazard in hell of making noticeable inroads against Windows." (The infamous John Dodge hatchet job, PC Week, June 8).

    The Open Group offers the possibility of Unix 98 certification to Linux at the Uniforum meeting. The resulting press release says "Since the Linux OS is proving to breathe increasingly tense competition for NT in this marketspace, it's in the best interest of complete Unix vendors for Linux to fetch branded so that it may compete more effectively and hold the low discontinue UNIX 98-compliant." Very exiguous is heard thereafter.

    The Gartner Group says there is exiguous hope for free software. "...these operating systems will not find widespread consume in mainstream commercial applications in the next three years, nor will there breathe broad third-party application support."

    [Wilbur] The Gimp 1.0 is released. This long-awaited release of one of Linux's highest profile tools did not disappoint.

    Stable kernel 2.0.34 is released after a long prepatch series.

    [Beowulf] The Beowulf web site shuts down temporarily due to concerns about U.S. export restrictions. Suddenly anybody can create a supercomputer, and people are getting worried. note this Dr. Dobbs article for some more background.

    Symantec tips hand on CDP roadmap | killexams.com true questions and Pass4sure dumps

    LAS VEGAS -- It's no furtive that Symantec Corp. plans to incorporate the continuous data protection (CDP) assets it bought with Revivio Inc. in November into its NetBackup product, but further details were not made publicly available until discussions Wednesday afternoon at the company's annual Vision conference.

    According to Sean Macnew, senior director of the CDP and replication product group for Symantec, the company's Continuous Data Protection and Replication (CDP/R) product is currently being developed as a "joint venture" between his group and the NetBackup group. Each group, he said, has committed 10 engineers to the project, and 10 engineers from Revivio are furthermore piece of the team.

    Symantec is planning to beta test the initial integration of the CDP feature with version 6.0 of NetBackup in August. That integration will allow NetBackup 6.0 users to request snapshots from any point in time from the CDP/R repository. Configuration of the CDP/R repository will breathe managed in its own divide console, called CDP/R Recovery Manager.

    "This way, if the storage administrator controls the CDP/R repository, the NetBackup administrator can noiseless Take data from it," Macnew said.

    For the release of version 6.5.2 of NetBackup, slated for Jan. 2008, NetBackup's Enterprise Disk Foundation, which controls policy-based lifecycle management features, will breathe able to request point-in-time snapshots from the CDP/R repository and automatically hotfoot them to other repositories. However, NetBackup 6.5 will not breathe able to control the configuration of the CDP/R repository, including which hosts and applications are protected using CDP.

    Also, once the snapshot schedule is set within NetBackup, for example, for a snapshot every four hours, the user would not breathe able to retroactively change the policy and receive snapshots from every two hours at a later time. The CDP/R repository will noiseless record every changed block, and applications will breathe recoverable from any point in time, but only within the CDP/R repository in that case.

    According to Macnew, this is due to a fundamental contrast between the NetBackup and CDP/R interfaces. "NetBackup can only note point-in-time objects," Macnew said, whereas CDP/R will breathe able to note data grouped by application on an object-oriented basis. "NetBackup will always exigency a quiesced, point-in-time view of a backup image," Macnew said.

    But, by the time NetBackup 7.0 is released (slated for 2009), CDP/R Recovery Manager will become a "pane" within the NetBackup management console. Once that happens, NetBackup will breathe fully able to configure CDP/R and absorb an application-oriented view of its backups.

    "The CDP/R console will become piece of a DR-oriented option within the NetBackup management GUI," Macnew said.

    Integration with Storage Foundation, Volume Manager, Veritas Cluster Server

    The next step after integration with NetBackup will breathe integration with Storage Foundation version 6.0. This will allow users to configure an application-oriented view of replication for disaster recovery, and furthermore accomplish Symantec's replication more granular using CDP, which functions at the obscure level, rather than traditional replication, which functions at the byte level.

    Symantec has changed the Revivio software so that CDP happens asynchronously and out-of-band in order to avoid performance bottlenecks in high-performing applications. In the first integration with Storage Foundation, users will absorb to consume a host-splitter driver to dispatch CDP data to the CDP/R repository.

    However, by next year, there will breathe integration with Veritas Volume Manager, which will eradicate the exigency for the divide driver. Integration with volume manager will furthermore affect that CDP policies can breathe set by volume, rather than disk or LUN.

    "It's easier to set up CDP at the volume flush because the volume flush is the logical protest you protect," Macnew said. "If you're protecting by LUN or disk, as file systems grow, administrators can forget to add modern LUNs to the CDP group."

    The final integration, Macnew said, will breathe with Veritas Cluster Server (VCS), furthermore slated for next year, in version 2.1 of CDP/R. VCS has replication management as piece of its Global Cluster feature, and the integration will allow VCS to control CDP/R replication. CDP/R will furthermore breathe integrated with the VCS Fire Drill feature, which will allow users to create virtual point-in-time images for test environments without reserving storage space for another snapshot.

    Partner reaction

    At least one of Symantec's commerce partners is not pleased with the timeline of integration with NetBackup -- even if it's as soon as later this year. "They bought Revivio six months ago, and Revivio already had a product on the market," said Mahesh Vaidyanathan, senior manager, solutions architecture, for STME, Symantec's largest channel partner in the Middle East.

    "EMC [Corp.] is pushing Kashya, and [Network Appliance Inc.] is pushing Topio," Vaidyanathan said. "We're quite keen on Symantec having this product out, otherwise they may absorb to search for other solutions to tender customers."

    "In large enterprises, CDP is only just starting to find a market," Macnew argued, adding that Symantec has had CDP for smaller enterprises as piece of Backup Exec, since October 2005. He added, "Users don't want to buy another point solution; they don't want to release this unless it's integrated with other products."

    New utilities for Storage Foundation

    Also being discussed on the reveal floor at Vision were modern utilities coming for Storage Foundation in future releases, including a modern Linux installation utility, which is in the early stages of evolution and is currently dubbed Prep Utility.

    The utility will port complete of Symantec's compatibility lists for servers, operating systems and storage into a free software utility that will breathe downloadable from Symantec's Web site, as well as packaged with Storage Foundation, according to William Lang, principal software engineer for Symantec, who is currently putting together the code for the utility.

    Storage Foundation has divide editions for Linux and Windows, Lang said, and the Windows version has its own compatibility discovery engine through Microsoft. "Eventually, they hope to build compatibility information into Storage Foundation from complete OS types," said Jeff Martin, group product manager, storage and server management group. "That's noiseless a vision, though it's not known yet what the technical challenges will be."

    Still, Lang and Martin said they hope the modern utility will provide a "one-stop shop" for users looking for compatibility information, rather than the process today, which requires searching through Symantec's Web site for compatibility information. The utility is furthermore slated to comprise direct links to "ReadMe" information about each product or patch in the compatibility matrix.

    Another feature that's coming will breathe a change to the Storage Foundation dynamic multipathing (DMP) process, which currently accesses third-party vendors' host bus adapter (HBA) drivers. The next version of Storage Foundation, Martins said, will access SCSI drivers in the server directly, improving performance.

    Martin said Symantec is currently looking for users to participate in focus groups and beta tests of the modern Prep Utility this summer. Interested users can contact Symantec.
